A new improved synthesis of the cis isomer of the honey bee, Apis mellifera L. (Hymenoptera: Apidae), queen substance, trans -9-oxo-2-decenoic acid, is described. The cis acid is somewhat active as an inhibitor of queen cell construction in honey bee colonies because small amounts are converted to the active trans isomer. Drone honey bees are not attracted to the cis acid. After prolonged exposure to sunlight, the cis isomer is photoisomerized to the active sex attractant, trans queen substance. The cis -9-oxo-2-decenoic acid does not mask ihc sex attractant activity of its geometric isomer during short-term exposures of lures containing 1:1 mixtures of both isomers.

cis-9-Oxo-2-decenoic Acid：作为蜜蜂信息素和掩蔽剂的合成和评价

描述了蜜蜂的顺式异构体 (Apis mellifera L. (膜翅目：蜜蜂科)，蜂王物质，反式 -9-氧代-2-癸烯酸) 的一种新的改进合成方法。顺式酸作为蜜蜂蜂群中蜂王细胞构建的抑制剂具有一定的活性，因为少量会转化为活性反式异构体。雄蜂不会被顺式酸吸引。长时间暴露在阳光下后，顺式异构体被光异构化为活性性引诱剂，反式皇后物质。cis -9-oxo-2-decenoic acid 在短期暴露含有两种异构体 1:1 混合物的诱饵期间不会掩盖其几何异构体的 ihc 性引诱活性。
